Hello, NOOB here. I have a cloud instance of Confluence that I use for myself and a couple friends for engineering. I used draw.io in the past and love it so I wanted to add it to my instance. I opted for the 30 day free trial and it shows up under my instance under setting / Atlassian marketplace. I have never done any admin for Confluence in the past so I know nothing about setting up add ons. I really want the ability of using draw.io pretty nearly the same you would get if you go to draw.io but imbedded in my confluence so I do not have to hassle with using draw.io and not having it imbedded.
TL;DR is there a step by step for setting up draw.io for beginners to confluence?
I have scoured google and Atlassian help and am coming up empty handed.
